Abstract

A handwriting input apparatus and method are provided. The handwriting input apparatus includes: a touch screen configured to display a handwriting corresponding to a touch input; and a processor configured to generate a skeleton for the handwriting by performing text recognition with respect to the handwriting, correct a style of the handwriting based on the generated skeleton, apply a beautification effect to the corrected style of the handwriting, and control the touch screen to display the beautified handwriting.

First claim

What is claimed is:

1 . A handwriting input apparatus comprising:
a touch screen configured to display a handwriting corresponding to a touch input; and a processor configured to generate a skeleton for the handwriting by performing text recognition with respect to the handwriting, correct a style of the handwriting based on of the generated skeleton, apply a beautification effect to the corrected style of the handwriting, and control the touch screen to display the beautified handwriting.

2 . The handwriting input apparatus as claimed in claim 1 , wherein the processor is further configured to apply the beautification effect to the corrected style of the handwriting based on at least one of a pen-tip, a handwriting direction, and a handwriting speed.

3 . The handwriting input apparatus as claimed in claim 2 , wherein in response to the pen-tip to be applied to the handwriting being determined, the processor is further configured to beautify the style of the handwriting by changing a thickness of strokes that constitute the handwriting based on the determined pen-tip and at least one of the handwriting direction and the handwriting speed.

4 . The handwriting input apparatus as claimed in claim 2 , wherein the processor is further configured to beautify the style of the handwriting by changing and applying the pen-tip based on at least one of the handwriting direction and the handwriting speed, and by changing a thickness of strokes that constitute the handwriting based on the changed pen-tip.

5 . The handwriting input apparatus as claimed in claim 2 , wherein the processor is further configured to determine a language that corresponds to the handwriting by performing text recognition with respect to the handwriting, and apply the beautification effect in accordance with the determined language based on of at least one of the pen-tip, the handwriting direction, and the handwriting speed.

6 . The handwriting input apparatus as claimed in claim 2 , wherein the processor is further configured to analyze a connected handwriting structure with respect to the handwriting, determine the pen-tip to be applied to the handwriting based on the analyzed connected handwriting structure, and apply the beautification effect based on the determined pen-tip and at least one of the handwriting direction and the handwriting speed.

7 . The handwriting input apparatus as claimed in claim 2 , wherein the processor is further configured to beautify the style of the handwriting by determining whether the handwriting includes capital or lowercase letters, determining the pen-tip to be applied to the handwriting based on a result of the determination and an analyzed connected handwriting structure, and applying the beautification effect based on at least one of the handwriting direction and the handwriting speed.

8 . The handwriting input apparatus as claimed in claim 1 , wherein the processor is further configured to convert the handwriting into a text having a predetermined font by performing the text recognition with respect to the handwriting, generate the skeleton based on an outline of the predetermined font, and correct the style of the handwriting by correcting strokes of the handwriting based on strokes of the generated skeleton.

9 . The handwriting input apparatus as claimed in claim 1 , further comprising a storage,
wherein the processor is further configured to store, in the storage, beautification information that includes at least one of sampling point information constituting strokes of the beautified handwriting, a layout of the beautified handwriting, color information of the beautified handwriting, coordinate information of the beautified handwriting, and beautification effect information of the handwriting.

10 . A method for controlling a handwriting input apparatus having a touch screen, comprising:
receiving a handwriting corresponding to a touch input on the touch screen; generating a skeleton for the handwriting by performing text recognition with respect to the handwriting; correcting a style of the handwriting based on the generated skeleton; applying a beautification effect to the corrected style of the handwriting; and displaying, on the touch screen, the beautified handwriting.

11 . The method as claimed in claim 10 , wherein the applying applies the beautification effect to the corrected style of the handwriting based on at least one of a pen-tip, a handwriting direction, and a handwriting speed.

12 . The method as claimed in claim 11 , wherein in response to the pen-tip to be applied to the handwriting being determined, the applying beautifies the style of the handwriting by changing a thickness of strokes that constitute the handwriting based on the determined pen-tip and at least one of the handwriting direction and the handwriting speed.

13 . The method as claimed in claim 11 , wherein the applying beautifies the style of the handwriting by changing and applying the pen-tip based on at least one of the handwriting direction and the handwriting speed, and by changing a thickness of strokes that constitute the handwriting based on the changed pen-tip.

14 . The method as claimed in claim 11 , wherein the applying determines a language that corresponds to the handwriting by performing text recognition with respect to the handwriting, and applies the beautification effect in accordance with the determined language based on at least one of the pen-tip, the handwriting direction, and the handwriting speed.

15 . The method as claimed in claim 11 , wherein the applying analyzes a connected handwriting structure with respect to the handwriting, determines the pen-tip to be applied to the handwriting based on the analyzed connected handwriting structure, and applies the beautification effect based on the determined pen-tip and at least one of the handwriting direction and the handwriting speed.

16 . The method as claimed in claim 11 , wherein the applying beautifies the style of the handwriting by determining whether the handwriting includes capital or lowercase letters, determining the pen-tip to be applied to the handwriting based on a result of the determination and an analyzed connected handwriting structure, and applying the beautification effect based on at least one of the handwriting direction and the handwriting speed.

17 . The method as claimed in claim 10 , wherein the correcting converts the handwriting into a text having a predetermined font by performing the text recognition with respect to the handwriting, generates the skeleton based on an outline of the predetermined font, and corrects the style of the handwriting by correcting strokes of the handwriting based on strokes of the generated skeleton.

18 . The method as claimed in claim 10 , further comprising storing beautification information that includes at least one of sampling point information constituting strokes of the beautified handwriting, a layout of the beautified handwriting, color information of the beautified handwriting, coordinate information of the beautified handwriting, and beautification effect information of the handwriting.

19 . A device comprising:
a touch screen configured to receive a handwriting from a user; and a processor configured to convert the handwriting into text having a predetermined font, generate a skeleton based on an outline of the text, correct a style of the handwriting based on a comparison between strokes of the handwriting and strokes of the generated skeleton, apply a beautification effect to the corr
